6-3: This process is used by cells to manufacture _biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products__

The purpose of this experiment was to explore the properties of chemical substances that can be used to identify the types of bonds in a chemical substance using a laboratory procedure. The two types of bonds being identified were ionic and covalent. Based on a substance’s properties, how can you determine whether its bonds are ionic or covalent? This is the question I posed before starting the experiment.

3. Do you think sugar or salt will melt at a higher temperature? Explain your answer.

Procedure- The procedure for this lab includes many simple steps and a few different things we are testing. Our first Procedure was to combine water and salt to see what kind of reaction it would make. First we fill the graduated cylinder with 100 ml of water. We then measured 1.0 grams of table salt on a balance to get an accurate amount. After, we took the measured amount of salt and poured it into the water filled beaker. Lastly, we watched and recorded the reaction.

The mixture was heated at 120°C using an aluminum block and was stirred gently. After all of the solid dissolved, it was heated for 20 additional minutes to ensure the reaction was complete.

Substances A and B have an appearance of a white solid like. Substances A and B were put into a test tube and on the Bunsen burner. As a result, B melted faster than A. A was slow to melt. The reason why B melted faster than A is because it has a lower boiling point than substance A which made it melt faster. It also shows that A needs more energy than B to be broken down.

This paper describes the methods used in the identification, investigation of properties, and synthesis of an unknown compound. The compound was identified as calcium nitrate by a variety of tests. When the compound was received, it was already known to be one of twelve possible ionic compounds. The flame test identified the presence of the calcium anion in the compound. The compound tested positive for the nitrate cation using the iron sulfate test. At this point it was hypothesized that the compound was calcium nitrate. Reactivity tests and quantitative analysis comparing the unknown compound with calcium nitrate supported this hypothesis. Synthesis reactions were then carried out and analyzed.

In this lab we performed four test. Using these test we discovered how the chemicals compounds Citric Acid, Calcium Chloride, Sucrose, Potassium Iodine, Phenyl Salicylate , and Sodium Chloride reacted to heat and many solutions. We also noticed that Phenyl salicylate was the least reactive out of all chemical compounds. Using the information discovered from the lab we were able to separate the chemical compounds into two groups. In group one were the chemical compounds Calcium chloride, Citric acid, Potassium iodide, Sodium chloride, and Sucrose these chemical compounds reacted to three of the four test. Group two was just Phenyl salicylate which reacted to only one of the four test. We also were able to state that group one was a covalent compound group and, group two was an ionic compound

During this investigation the question we looked to answer was: what are the identities of the unknown compounds? In an effort to answer the question, our group designed a method in which the relationships between the unknown compounds in plastic bags were compared so that their identities could be determined. The mole (mol) provides a measure of the number of atoms present in the sample of a compound. One mole of an element or compound contains

Ionic compounds have the characteristics of having a crystalline structure, a brittle and hard texture, not being able to burn easily, and high melting and boiling points. They also have the ability to conduct electricity when melted or dissolved in distilled water. Covalent compounds are the complete opposite having opposite characteristics. Covalent compounds have low melting

The guiding question of this ADI lab was, “What are the identities of the unknown compounds?” The goal of this lab was to understand the relationships between moles and molar mass to find the identity of unknown compounds. The mole can be used to measure small amounts of a substance or is used to convert from unit to unit using dimensional analysis. One mole is equivalent to the molar mass in grams of that substance. If you start with the moles of an unknown substance, multiply it by a given compound’s molar mass, and then divide it by however many moles are in the compound of your choice, you will get the mass of the compound. With that answer you can then compare with mass of the compound in the bag to determine its identity. We first started

The styrofoam cups were used to store the acid (cup was labeled A) and base (cup was labeled B) prepare for them to be mixed. A lid was put on cup A and then the temperature probe was inserted to begin to measure the temperature

Once the range is obtained, remove the thermometer and beaker. Pour out the hot water and allow both the thermometer and the beaker to cool. Once cool, repeat the previous steps with the second compound, tetradecanol. At the conclusion of the second experiment, repeat the steps for a third and final time using an equal mixture of both compounds. Be sure to record the melting point range for all three experiments.
